Fuseholders are a type of electrical equipment that is designed to protect sensitive electrical components and circuits from potentially hazardous voltage levels. The HPV-DV-20A fuseholder is a popular type of fuseholder, used in low-voltage applications to provide the same level of protection. It is designed for use with an HRC fuse link, and consists of two parts: the fuseholder itself and a clip and ring.

An HRC fuse link is a form of fast-acting, thermal-type fuse, and the HPV-DV-20A fuseholder is designed to suit this type of fuse. The clip is mounted on the fuseholder and held in place by three screws, with its two ends forming a ring around the fuse. This ensures that it stays firmly in place during operation, providing a secure connection between the fuse and the fuse holder. The clip and ring are connected to a plastic insulating cover, which provides insulation and protection from shocks or other dangers.

The HPV-DV-20A is designed to be used in a range of low-voltage applications, such as commercial and industrial lighting, electrical motors, and machine control equipment. It is designed to operate in temperatures between -40 degrees Celsius and +105 degrees Celsius, which makes it suitable for both indoor and outdoor applications. The fuseholder is also designed to be robust and durable, with a solid, corrosion-resistant construction. This makes it ideal for use in harsh environmental conditions.

The working principle of the HPV-DV-20A is quite simple. When the fuse in the holder receives an over-current, the fuse heats up quickly, which causes the link to melt and disconnect the circuit. This stops the flow of electricity and protects the equipment from damage or destruction. The fuse holder also provides short-circuit protection, as the fuse cuts off the current in case of a short-circuit. It also provides surge protection, by limiting the current in case of an especially high surge.

The HPV-DV-20A fuseholder is a reliable and efficient way of providing protection in low-voltage applications. Its robust construction makes it suitable for use in harsh environments, while its simplicity makes it easy to install and use. The HRC fuse link is the only type of fuse that it can be used with, but this provides a secure connection and a high level of protection.
